General Requirements for Using the FA-M3 / e-RT3 Controller
Set the product in a location that fulfills the following requirements:
- Where the product will not be exposed to direct sunlight, and where the operating
surrounding air temperature is from 0°C to 55°C (32°F to 131°F).
There are modules that must be used in an environment where the operating
surrounding air temperature is in a range smaller than 0°C to 55°C (32°F to 131°F).
Refer to “Hardware Manual” (IM 34M06C11-01E) or the applicable user's manual. In
case of attaching such a module, the entire system's operating surrounding air
temperature is limited to the module's individual operating surrounding air
temperature.
- Where the relative humidity is from 10 to 90%.
In places where there is a chance of condensation, use a space heater or the like to
constantly keep the product warm and prevent condensation.
- For use in Pollution Degree 2 Environment.
- Where there are no corrosive or flammable gases.
- Where the product will not be exposed to mechanical vibration or shock that exceed
specifications.
- Where there is no chance the product may be exposed to radioactivity.
Use the correct types of wire for external wiring:
- USE COPPER CONDUCTORS ONLY.
- Use conductors with temperature rating above 75°C.
Securely tighten screws:
- Securely tighten module mounting screws and terminal screws to avoid problems
such as faulty operation.
- Tighten terminal block screws with the correct tightening torque as given in this
manual. Refer to the “Hardware Manual” (IM 34M06C11-01E) or the applicable
user's manual for the appropriate tightening torque.
Securely lock connecting cables:
- Securely lock the connectors of cables, and check them thoroughly before turning
on the power.
Interlock with emergency-stop circuitry using external relays:
- Equipment incorporating the FA-M3 / e-RT3 controller must be furnished with
emergency-stop circuitry that uses external relays. This circuitry should be set up to
interlock correctly with controller status (stop/run).
Ground for low impedance:
- For safety reasons, connect the [FG] grounding terminal to a protective earth
(Comply with the regulation of each country.). For compliance to CE Marking, use
braided or other wires that can ensure low impedance even at high frequencies for
grounding.
Configure and route cables with noise control considerations:
- Perform installation and wiring that segregates system parts that may likely become
noise sources and system parts that are susceptible to noise. Segregation can be
achieved by measures such as segregating by distance, installing a filter or
segregating the grounding system.

vi
IM34M06H46-04E 2nd Edition : Jan.31, 2017-00
Configure for CE Marking Conformance:
-For compliance to CE Marking, perform installation and cable routing according to
the description on compliance to CE Marking in the “Hardware Manual” (IM
34M06C11-01E).
-The list of CE conforming models is available in Appendix A2. of “Hardware
Manual”.
Keep spare parts on hand:
- We recommend that you stock up on maintenance parts, including spare modules,
in advance.
- Preventive maintenance (replacement of the module) is required for using the
module beyond 10 years.
Discharge static electricity before touching the system:
- Because static charge can accumulate in dry conditions, first touch grounded metal
to discharge any static electricity before touching the system.
Wipe off dirt with a soft cloth:
- Gently wipe off dirt on the product's surfaces with a soft cloth.
- If you soak the cloth in water or a neutral detergent, tightly wring it out before wiping
the product. Letting water enter the module interior can cause malfunctions.
- Do not use volatile solvents such as benzine or paint thinner or chemicals for
cleaning, as they may cause deformity, discoloration, or malfunctioning.
Avoid storing the FA-M3 /e-RT3 controller in places with high
temperature or humidity:
- Since the CPU module has a built-in battery, avoid storage in places with high
temperature or humidity.
- Since the service life of the battery is drastically reduced by exposure to high
temperatures, take special care (storage surrounding air temperature should be
from -20°C to 75°C).
- There is a built-in lithium battery in a Sequence CPU module which serves as backup
power supply for programs, device information and configuration information.
The service life of this battery is more than 10 years in standby mode at room
temperature. Take note that the service life of the battery may be shortened when
installed or stored at locations of extreme low or high temperatures. Therefore, we
recommend that modules with built-in batteries be stored at room temperature.
Always turn off the power before installing or removing modules:
- Failing to turn off the power supply when installing or removing modules, may result
in damage.
Do not touch components in the module:
- In some modules you can remove the right-side cover and install ROM packs or
change switch settings. While doing this, do not touch any components on the
printed-circuit board, otherwise components may be damaged and modules may fail
to work.
Do not use unused terminals:
- Do not connect wires to unused terminals on a terminal block or in a connector.
Doing so may adversely affect the functions of the module.

vii
IM34M06H46-04E 2nd Edition : Jan.31, 2017-00
Use the following power source:
- Use only F3PU- as the power supply module.
- If using this product as a UL-approved product, for the external power supply, use a
limited voltage / current circuit power source or a Class 2 power source.
Refer to the user's manual before connecting wires:
- Refer to the “Hardware Manual” (IM 34M06C11-01E) or the applicable user’s
manual for the external wiring drawing.
- Refer to “A3.6.5 Connecting Output Devices” in the “Hardware Manual” before

1. Overview
The Yokogawa High-speed Link System (YHLS) master module F3LH01-1N has one
YHLS master interface port, while the F3LH02-1N has two master interface ports for
connecting slave units to perform remote I/O.
Table 1.1 Applicable Module
Model Code Module Name Description
F3LH01-1N YHLS Master Module One YHLS port
F3LH02-1N YHLS Master Module Two YHLS ports
1.1 What is YHLS?
Yokogawa High-speed Link System (YHLS) is designed for implementing high-speed
remote I/O in the FA-M3 system.
A YHLS system consists of the FA-M3 master module (F3LH0-1N) connected to
multiple distributed slave units through a communication cable to allow high-speed
control of remote I/O units from a sequence CPU. It has the following merits:
- High-speed scan of 63 slave units in just 0.96 ms.
- Reduced wiring through use of distributed devices within a system
- Simple mechanism for high-speed exchange of ON/OFF signals and numerical data
with remote devices
- Adoption of the HLS open network allows flexibility in building customized
application systems by connecting HLS-compliant I/O units from different vendors.

IM34M06H46-04E 2nd Edition : Jan.31, 2017-00
1.2 Features of YHLS
1.2.1 Communications between YHLS Master Module and
Slave Units
Through periodic communications with connected slave units, the YHLS master module
acquires ON/OFF information of switches connected to these slave units into its input
data area, as well as outputs information stored in its output data area as ON/OFF
information for actuators. By accessing the I/O data areas of the YHLS master module
using READ and WRITE instructions, the sequence CPU module can thus exchange
information with field equipment.

1.2.2 Constant Communication Cycle Time
YHLS features a constant communication cycle time, not affected by automatic
participation or withdrawal of slave units, thus delivering reliable communications with
constant cycle time under all circumstances.
1.2.3 Output Control Function
The YHLS master module can be made to suspend YHLS communications when the
sequence CPU module “stops”. By combining this feature with output control functions
of individual slave units, which can be used to reset or hold the contact outputs of
individual slave units when YHLS communication stops, you can implement output
control of the entire YHLS system when sequence stops.
1.2.4 Daisy-chain Connection
As YHLS adopts a daisy-chain connection inside each communication connector, a
slave unit that is powered off or down does not affect normal communication with the
other slaves.
1.2.5 Transmission Line Quality Indicators
The YHLS master module indicates transmission line quality using its L (LINK) LED and
A (ALARM) LED. It also stores transmission line quality status information in its internal
registers.
